Tobermorite and katoite were formed as binding phases in bricks. Single axis compressive strength of the bricks was 76.5 kg f/cm 2. The thermal conductivity of the bricks were measured as 0.225 W m À1 K À1. a b s t r a c t Fly ash is one of the coal combustion products (CCPs) of coal burning power plants and it contains substantial amounts of potentially harmful constituents to the environment. It is known that nearly 600 million tons of fly ash is produced in the world per-annum. In Turkey, the annual production of fly ash is, on average, 13 million tons and only a small amount of this is utilized. This study examines the production of lightweight , high thermal insulating bricks made out of the fly ash and lime. Cylindrical brick samples were produced through steam curing of Seyitömer thermal power plant fly ash and lime mixtures in an autoclave in order to determine the optimum conditions for mechanically sound bricks. Subsequently, at the optimum conditions determined, real-size bricks were produced and subjected to standard tests. The findings of this paper suggest that fly ash/lime bricks can be an alternative product to aerated cellular concrete.

This study aims to establish a fine coal recovery process of very high efficiency at reasonable capital investment and operational costs. The technical feasibility to upgrade the properties of the predeslimed fine refuse of a lignite washing plant with 35.9%

For this purpose, a se¬ries of separation tests were conducted using a pilot scale heavy media separation drum. Based on the obtained upgrading results the washability of the test coal is evaluated. Fur¬thermore, for different clean coal qualities, the expected upgrading results are computed un¬der consideration of the actual test results.
